Windows 7: computer won't boot after changing RAM speed in Bios (tried CMOS rest)

computer won't boot after changing RAM speed in Bios (tried CMOS rest)

I changed my RAM speed in bios from 2133 to 3200 using the XMP settings. At first it didn't save when I tried to restart it so I changed it again. Then when I tried to restart the computer it wouldn't boot up. The monitors, mouse and keyboard won't turn on but the LED's and fan in the computer are on. I also noticed there's a little orange light on the bottom right which is supposed to indicate there's a CPU detection failure? is it possible it could have fried?

-Tried removing CMOS battery for an hour
-Tried 1 RAM stick/switching RAM around (I don't have any extra RAM to test)
-Reseated CPU, GPU and replugged everything
-Holding power button down while unplugged
-Shorting the jumper w/screw driver
This motherboard has a switch that's supposed to let me boot from backup bios also but it's not working either.

System Builder - Ryzen 7 1700X 3.4GHz 8-Core, GeForce GTX 1080 Ti 11GB Aorus Waterforce Xtreme Edition - PCPartPicker

any help is appreciated.

What is your post code on the board besides the lights, when you press the bios swap switch what light is on on the middle of the board showing what bios is active? If you try to boot without any ram in it do you get a post code for ram missing?

Take the RAM out, take out the CMOS battery, unplug the computer, and then do a BIOS reset.

Now reinstall the RAM and the CMOS battery, and you should be able to operate as normal.
